1. If you want to talk about tesseract performance you should get rid of all that wrappers around (you are wrapping tesseract with python library, and you put it to python app, then you all that put to webserver...)
2. Next: provide a testing case so others can check your performance measurements. 3. If you are caring about OCR performance you should use the tesseract library directly, e.g. for python https://github.com/sirfz/tesserocr. pytesseract just wrap tesseract executable, so each time you need to OCR something you waste time with init process...
